Frequently asked questions
Does this edit original PDF text?
No. Text stamps and signatures are overlays on top of pages.
Is a drawn signature legally a digital signature?
No. This tool only embeds an image. It does not use certificates, PAdES, or TSA.
Are files uploaded?
Files never leave your browser.
What happens when I rotate a page?
Overlays and crop on that page are cleared so placement does not drift.
Is crop the same as redact?
No. Crop only changes visible page boxes; underlying content may still exist.
In what order are edits applied?
Organize pages → crop → text/signature overlays → watermark → page numbers.
